4 RUBBER INSULATING GLOVES Arc Flash Protection - Leather Protectors ASTM F Significance and Use 3.1 The purpose of the leather protectors is to provide mechanical protection only for the rubber insulating gloves and rubber insulating mittens. Table 130.7(C)(10) Note 2 If rubber insulating gloves with leather protectors are required by table 130.7(C)(9). Additional leather or arc-rated gloves are not required. The combination of rubber insulating gloves with leather protectors satisfies the arc flash protection requirement.

5 RUBBER INSULATING GOODS Table 130.7(C)(6)(c) Maximum Test Intervals Rubber Insulating Equipment When to Test Blankets Before first issue; every 12 months thereafter Covers If insulating value is suspect Gloves Before first issue; every 6 months thereafter Line Hose If insulating value is suspect Sleeves Before first issue; every 12 months thereafter Governing Standard for Test Voltage ASTM F 479 ASTM F 478 ASTM F 496 ASTM F 478 ASTM F 496 If the insulating equipment has been electrically tested but not issued for service, it may not be placed into service unless it has been electrically tested within the previous 12 months.

6 RUBBER INSULATING GLOVES SELECTION Common Tasks Voltage testing Work on utilization equipment fed directly by a branch circuit of the panel board CB or fuse switch operation with covers open Insertion or removal of individual starter buckets from MCC

7 RUBBER INSULATING GLOVES CARE Keep them clean Keep them dry Keep them cool Avoid harsh solvents when washing hands Avoid contact with petroleum products Store away from direct sunlight Do not store inside out When hung from belt in canvas storage bag - fingers up! Store horizontally

8 RUBBER INSULATING GLOVES CARE Inspection Tears, punctures, or cuts Ozone cutting or checking Embedded foreign objects Texture changes Swelling Softening Hardening Sticky Inelastic Contamination

9 RUBBER INSULATING GLOVES CARE Air test before each day s use Maximum inflation size Type I: 1.5 times normal Type II: 1.25 times normal

10 RUBBER INSULATING GLOVES CARE Suggestion for a smooth testing transition 0 and 00 Gloves available in multiple colors (orange, black, yellow) Alternate colors between testing period Mass collection of gloves requiring recertification Mass re-issue of new/certified gloves (ex. Jan 1 thru June 30 Yellow July 1 thru Dec 31 Orange) Allows supervisor to determine employee compliance at-a-glance

14 Recommend all qualified personnel dress to category 0 at all times Leather gloves as needed (Note 2 Rubber insulating gloves with leather protectors are required and satisfy the arc flash protection requirement.) HAZARD RISK CATEGORY 0

15 HAZARD RISK CATEGORY 1 Significant changes from Category 0 Clothing must have a cal/cm² rating of 4 Requirement of ARC Rated Face Shield and Hard Hat (Note 7 A face shield with a minimum arc rating of 4 with wrap-around guarding to protect not only the face, but also the forehead, ears, and neck) Leather work shoes (As Needed)

16 HAZARD RISK CATEGORY 2 & 2* Significant changes from Category 1 Clothing must have a cal/cm² rating of 8 Additional head and neck coverage Leather work shoes HRC2 Requirement of ARC Rated Face Shield or Flash Suit Hood and Hard Hat (Note 7 A face shield with a minimum arc rating of 8 with wrap-around guarding to protect not only the face, but also the forehead, ears, and neck) HRC2* Requirement of ARC Rated Flash Suit Hood (Note 10 Alternate is to use a face shield with a minimum arc rating of 8 and a balaclava (sock hood) with a minimum arc rating of 8 which covers the face, head and neck except for the eye and nose area)

17 HAZARD RISK CATEGORY 3 Significant changes from Category 2 Clothing must have a minimum cal/cm² rating of 25 (Note 8) Upgrade of head and face protection to a multi-layer flash hood Arc Rated Gloves as needed (Note 2 If rubber insulating gloves with leather protectors are required, additional leather protectors satisfy the arc flash protection requirement.)

18 HAZARD RISK CATEGORY 4 Significant changes from Category 3 Clothing must have a minimum cal/cm² rating of 40 (Note 9)

19 PERSONAL PROTECTIVE EQUIPMENT Material Selection FR Treated Cotton Indura (100% Cotton) Indura Ultra Soft (88% Cotton / 12% polyamide blend) Guaranteed FR for the life of the garment Nomex IIIa Blended for comfort (varying) Most Durable Protera Made by Dupont Does not wash out

20 PERSONAL PROTECTIVE EQUIPMENT CARE NFPA 70E (C) (16) Care and Maintenance of FR Clothing and FR Arc Flash Suites (a) FR apparel shall be inspected before each use. (b) The garment manufacturer care and maintenance instructions shall be followed (c) FR apparel shall be stored in a manner that prevents physical damage (d) Cleaning, Repairing, and Affixing items Follow manufacturer s instruction when cleaning Same FR material must be used for all repairs Use ASTM F 1506 for affixed trim, name tags, or logos

21 PERSONAL PROTECTIVE EQUIPMENT CARE Washing Soft water is highly recommended Use a light soil formula with a quality detergent Maximum water temperature is 120 F Do not use chlorine bleach (sodium hypochlorite) or hydrogen peroxide either separately or in a detergent Do not use tallow (animal fat based) soap Do not use fabric softener of any kind (as published by WESTEX INC.)

22 PERSONAL PROTECTIVE EQUIPMENT CARE Drying Use minimum temperature Remove clothing when dry or slightly damp Do not over dry (excessive shrinkage) May be pressed or ironed on cotton setting

23 PERSONAL PROTECTIVE EQUIPMENT 130.7(C)(9) VS. IEEE (C)(9) Pay attention to the notes! Clothing configuration must meet cal/cm² IEEE 1584: The PPE requirements will be specific PPE purchases can be specific to the need PPE will be adequate but not excessive PPE will meet the requirements of OSHA Most importantly PPE will protect the workers from recognized hazards

24 INSULATED TOOLS

25 INSULATED TOOLS NFPA 70E (D)(1)(a) Requirements for Insulated Tools NFPA 70E (A) Test Instruments and Equipment (1) Rating for circuits and equipment to which they will be connected (ANSI/ISA ( )/UL ) (2) Design for the environment to which exposed and manner in which they will be used (3) Visual Inspection a) Before each use b) Defect or damage remove from service c) Unusable until repair and recertification (4) Operation Verification when work 50V or more test operation before and after absence of voltage test is performed

26 INSULATED TOOLS Screwdrivers Nut drivers Pliers, Crimpers, and Strippers Interchangeable Tools Wrenches Composite Tools Specialty Tools Non-Sparking / Non-Magnetic Tools Took Kits Sticks and Hooks

27 INSULATED TOOLS SELECTION Quantity Additional on reserve for damage/loss Type based on importance of task Quality American made Properly ASTM tested Durability Size
